If you upgrade vSphere components separately from Horizon View components, you must back up some Horizon View data and reinstall some Horizon View software.

Instead of performing an integrated upgrade of Horizon View and vSphere components, you can choose to first upgrade all Horizon View components and then upgrade vSphere components, or the reverse. You might also upgrade only vSphere components when a new version or update of vSphere is released.

When you upgrade vSphere components separately from Horizon View components, you must perform the following additional tasks:

1

Before you upgrade vCenter Server, back up the vCenter Server database and the View Composer database.

2

Before you upgrade vCenter Server, back up the View LDAP database from a View Connection Server instance by using the vdmexport.exe utility.

For instructions, see the VMware Horizon View Administration document. If you have multiple instances of View Connection Server in a replicated group, you need to export the data from only one instance.

3

If you use View Composer, after you upgrade all ESX/ESXi hosts that are managed by a particular vCenter Server instance, restart the View Composer service on that host.

4

After you upgrade VMware Tools in virtual machines that are used as remote desktops, reinstall View Agent.

Reinstalling View Agent guarantees that the drivers in the virtual machine remain compatible with the other Horizon View components.

Step-by-step instructions for running the View Agent installer appear in Setting Up Desktop and Application Pools in VMware Horizon View.
